Prompt Optimization And Few Shot Learning

via “few-shot example sampling with stratification and caching”

EleutherAI's evaluation framework — 200+ benchmarks, powers Open LLM Leaderboard.

Unique: Integrates few-shot sampling directly into the request generation pipeline with built-in caching and stratification support. The system computes sampling once per task, caches results, and reuses them across all evaluation instances. Stratified sampling uses class labels to ensure balanced representation, which is critical for imbalanced datasets where random sampling might miss minority classes.

vs others: Provides stratified sampling (not just random) and automatic caching that alternatives like simple prompt engineering lack; integrates sampling into the evaluation pipeline rather than requiring manual example selection

via “few-shot example synthesis and selection”

Stanford framework that replaces manual prompting with automatically optimized LLM programs.

Unique: Automatically selects examples from training data based on metric-driven feedback, rather than relying on manual curation or random sampling. Advanced optimizers like GEPA can synthesize new examples using reflective reasoning, generating demonstrations that target specific failure modes.

vs others: More sophisticated than random example selection and more scalable than manual curation, DSPy's example synthesis integrates with the optimization loop to learn examples that maximize task-specific metrics.

TII's 180B model trained on curated RefinedWeb data.

Unique: Achieves few-shot learning through pure scale (180B parameters) and diverse training data (3.5T tokens) without explicit few-shot fine-tuning, enabling emergent task adaptation across arbitrary domains, though with less predictable performance than models explicitly optimized for in-context learning.

vs others: Larger parameter count enables better few-shot generalization than smaller models (LLaMA 70B), but lacks explicit in-context learning optimization that GPT-4 employs through instruction-tuning, potentially requiring more sophisticated prompt engineering to achieve comparable few-shot performance.
